This is the text of this hymn as it appears in an 1871 edition of the Supplemental Hymn and Tune Book (1868):

Sing Alleluia forth in duteous praise,
O citizens of heaven; in sweet notes raise
An endless Alleluia!

Ye next, who stand before th’ Eternal Light,
In hymning choirs re-echo to the Height
An endless Alleluia!

The Holy City shall take up your strain,
And with glad songs resounding, wake again
An endless Alleluia!

In blissful antiphons ye thus rejoice,
To render to the Lord with thankful voice
An endless Alleluia!

Ye who have gained at length your palms in bliss,
Victorious ones, your chant shall still be this—
An endless Alleluia!

From those exalted lips for ever ring
The strains which tell the honour of your King,
An endless Alleluia!

This is the rest for weary ones brought back;
This is the food and drink which none shall lack,–
An endless Alleluia.

While Thee, Creator of the world, we praise
For ever, and tell out in sweetest lays
An endless Alleluia.

To Thee, Eternal Son, our voices sing
With them, to Thee, O Holy Ghost we bring
An endless Alleluia. Amen.
